Students were inquired to answer a question at school and to mention what is most important for them to succeed. Of the numerous reactions, one that that stood out was practice. People who commonly successful do not become successful by being born. They work hard and dedicate their lives to succeeding. If you tend to obtain your goals, keep this in mind! in this article, are one of the answer and question example that you could certainly work with to practice and boost your practical knowledge and also give you insights that could assist you to sustain your study in school.
Question:
A 2000 kg car experiences a constant braking. force of 10,000 N, and comes to be a stop in 6. sec.. What would be the distance traveled by the. car in coming to rest?
Answer:
Given:
F = Force = 10000N
m = mass = 2000kg
t = time = 6 seconds
a = acceleration = ?
Using the formula: F = ma
10000 = 2000(a)
a = 5 m/s^2
Using the formula: Vf = Vo + at
Where: Vf = final velocity = 0
Vo = initial velocity = ?
0 = Vo + 5(6)
Vo = 30 m/s
Using the formula: s = (1/2)(Vf + Vo)(t)
s = (1/2)(30 + 0)(6)
s = 90
Therefore, the car would have traveled a distance of 90m before coming to rest.
From the answer and question examples above, hopefully, they can possibly guide the student resolve the question they had been looking for and observe of every single thing declared in the answer above. You might possibly then have a discussion with your classmate and continue the school learning by studying the problem together with each other.
